This is a strange one! I have programmed my cable box to record the entire series of This Old House on WNET 13 in NY. It simply will not record. I have to record one at a time. Any suggestions? This only happens with this show!
It will depend on how the show is scheduled and listed, and how the guide data is coded. This is most likely an issue with the Guide Data provided by a third party (i.e. - Gracenote)
For "series" recordings, the DVR needs the Season Number and the Episode Number of each show aired. If the guide data for the show doesn't include the Season and Episode number, the DVR doesn't know what to do, so it does nothing.
This problem also occurs when a DVR is set to record all games for a given sports team.
I had the same problem a couple years ago. Seemed to be related to the show being on multiple channels. I forced in the series options to only record on the one channel and it then worked.
